It would be useful to know what you've tried exactly ...

In any case, in a playback situation you usually want to

 - use GST_SEEK_FLAG_FLUSH | GST_SEEK_FLAG_KEY_UNIT
 - seek in GST_FORMAT_TIME (remember the time is in nanoseconds)
 - use gst_element_seek_simple()

you need to add

 `pkg-config --cflags gstreamer-plugins-base-0.10`

to your CFLAGS / compiler flags and

 `pkg-config --libs gstreamer-plugins-base-0.10 -lgstinterfaces-0.10`

to your LIBS / linker flags as per:
